BACKGROUND: Percutaneous mechanical thrombectomy (PMT) is commonly used to treat acute thrombotic syndromes. Angiojet (AJ) forcibly sprays fibrinolytics to fragment and aspirate thrombus. It's known to cause hemolysis and gross hematuria, yet potential consequences to renal function after AJ remain unstudied. We sought to determine the risk of acute kidney injury (AKI) after AJ when compared to other lysis techniques. METHODS AND RESULTS: We retrospectively reviewed patients treated with thrombolysis over 5 years...

BACKGROUND: Although recent guidelines recommend EVAR for robust younger patients, we have been limiting our indication to older patients or those who are physically frail. This study compares long-term outcomes of our series of abdominal aortic aneurysms (AAA) treated with endovascular repair (ER) and open surgery (OS), using propensity-score matching. METHODS: Between June 2007 and October 2014, 819 patients with infrarenal AAA underwent elective repair at our institution...

OBJECTIVES: The goal of this review is to give an overview of current results and role of the kissing stent (KS) technique in AIOD treatment. BACKGROUND: Endovascular treatment of aortoiliac occlusive disease (AIOD) involving the aortic bifurcation is challenging. The gold standard is open surgery with patency rates up to 90% at 5 years, but has considerable morbidity and mortality. The KS technique was introduced as an alternative. METHODS: The Cochrane guidelines were used to assure a systematic method...

Deep femoral artery pseusoaneurysms (DFAPs) are rare and generally occur after penetrating trauma or surgical procedures. A 36-year old obese man presented with pain in correspondence of the anterior-lateral thigh after 6 months from gunshot wound. Duplex and computed tomography (CT) showed a bilobed right DFAP (maximal diameter 12.9 cm). The patient was managed urgently, under local anaesthesia, by placement in the distal DFA of a Viabahn 8 x 100mm stent-graft (W L Gore & Associates, Inc). The post-operative course was uneventful and the 24-months CT showed regular stent-graft patency and 20 mm DFPA shrinkage...

INTRODUCTION: Aneurysm regression and target vessel patency during early and mid-term follow-up may be related to the effect of stent graft configuration on the anatomy. We quantified geometry and remodeling of the renal arteries and aneurysm following fenestrated (F-) or snorkel/chimney (Sn-) endovascular aneurysm repair (EVAR). METHODS: 29 patients (mean age, 76.8±7.8 years) treated with F- or Sn-EVAR underwent computed tomography angiography at pre-op, post-op, and follow-up...

PURPOSE: We present two different cases of chronic aortic dissection, where we opted to land the stent graft into the false lumen to treat the associated aneurysm. CASE DESCRIPTIONS: For the first case, the goal of thoracic endovascular aortic repair (TEVAR) was to exclude the aneurysm from within the false lumen, because of a slit-like true lumen. In the second case, the visceral arteries came off the false lumen, with the renal vessels from the true lumen. False lumen TEVAR was performed and the infra-renal aorta fenestrated, as to ensure adequate perfusion...

REVIEW
Luis Miguel Salmerón Febres, Jorge Cuenca Manteca
Anticoagulation is the treatment of choice in the management of venous thromboembolic disease. This approach is applied to reduce mortality and the risk of recurrences and associated complications. Standard therapy for non-oncologic patients has traditionally been based on parenteral anticoagulation followed by vitamin K antagonists. However, this approach has many limitations. Direct oral anticoagulants have many advantages over standard therapy. While they are equally effective as standard therapy for reducing the possibility of recurrence of venous thromboembolic disease, they carry a lower risk of major bleeding...

PURPOSE: We aimed to identify predictors of stable aortic dimensions in medically managed type B aortic dissections (TBAD). METHODS: Medically managed TBAD patients from the International Registry of Acute Aortic Dissection (IRAD) with available aortic measurements at up to 24 months were included. Growth rate was calculated by dividing the largest descending diameter at the latest endpoint not influenced by intervention minus initial descending diameter, by the recorded time interval...

Blunt thoracic aortic injury (BTAI) in a patient with an aberrant right subclavian artery (ARSA) presents unique challenges for patient management and aortic repair. Specific considerations include the need to treat coincidental ARSA, subclavian revascularization, and ARSA exclusion. Despite the rise of endovascular endovascular repair as the primary modality for aortic repair for BTAI, reports of this technique in the setting of ARSA are limited. Here we describe three patients with ARSA who underwent TEVAR for BTAI, and discuss critical management and technical issues in these patients...

A pediatric patient with critical limb ischemia secondary to antiphospholipid syndrome (APS) is reported. A 14-year-old male underwent extensive evaluation for worsening right lower extremity pain and ulcerative lesions of his right foot. He was discovered to have proximal occlusion of the superficial femoral artery (SFA), the distal popliteal artery, the anterior tibial artery at the mid-calf, and the posterior tibial artery at the ankle. Laboratory analysis revealed a diagnosis of APS, and he underwent a common femoral artery to above-knee-popliteal artery bypass with reversed greater saphenous graft...

BACKGROUND: A majority of patients undergoing lower limb amputations have diabetes or peripheral artery disease. Despite improvements in care, there remains a substantial perioperative mortality associated with these procedures. Less well-defined is the mortality risk to these patients going forward, once outside the perioperative period. The aim of this systematic review is to summarize and pool the available data in order to determine the long term mortality associated with amputation in the diabetic and peripheral vascular patient, as well as to define specific factors associated with increased mortality risk...

BACKGROUND: Cigarette smoking is strongly associated with atherosclerotic disease. It is incumbent upon vascular surgeons to provide smoking cessation counseling to their patients. The objective of this study was to determine the association of smoking cessation counseling (SCC) and improvement in quality of care. METHODS: As a quality project using retrospective data, the study received IRB exemption status. A retrospective review of prospectively maintained database from April 2014 through March 2015 of outpatient encounters in a vascular surgery clinic was performed of current smokers...

Type II endoleak is the most frequent procedure-related complication during endovascular aneurysm exclusion. Actually there is little controversy in the management of type I and III endoleak, while type II endoleak still generates conflicting reports about their timing and type of treatment. Currently, the intervention is needed only in case of sac enlargement, but not in case of persistent endoleak alone. We report the case of a 77 year-old man treated with a custom-made branched/fenestrated endograft for a type III thoracoabdominal aortic aneurysm...

INTRODUCTION: Thoracic endovascular aortic repair (TEVAR) can be complicated by graft collapse, endoleaks, and stent migration. The incidence of these complications and other outcomes is poorly understood in young trauma victims who receive endovascular aortic repair of blunt thoracic aortic injury. REPORT: A 29 year-old pedestrian was struck by a vehicle resulting in polytrauma including blunt thoracic aortic injury (BTAI) with transection distal to the left subclavian artery origin...

INTRODUCTION: One of the main advantages of endovascular abdominal aortic aneurysm repair (EVAR) is shorter post-operative hospital length of stay (LOS) compared to open repair. However, patients with pre-existing conditions may be predisposed to a protracted LOS. Our aim was to identify pre-operative risk factors for prolonged post-operative LOS after elective EVAR. METHODS: The American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP) database (2005-2013) was used to analyze all patients undergoing elective EVAR without adjunctive procedures...
